In the dimensioning module, a DUENQ cross-section is classified as an invalid cross-section type and dimensioning is therefore not possible. What is the reason?

Answer

The DUENQ cross-section consists of several non-contiguous partial cross-sections, so that in DUENQ it is calculated according to the theory of stiffening systems. DUENQ also gives a hint before the calculation. The dimensioning of such cross sections is not possible in add-on modules such as RF / STEEL EC3, RF / ALUMINUM etc.
In most cases, however, the cross-sectional parts should be connected to each other. The FAQ describes how this connection can be modeled.
